Great country. Iused to work nearby at Lochinver. You can fish on many of the local lochs for a small permit charge.
Wild camping no problem under the Land Reform Act.
Achmelvich Youth hostel is pretty good. Nice beach there.
Suilven itself looks impossible from a distance but the conventional route is actually completely straightforward. In summer, anyway.
